lporation of Illinois 111., a cor- Application November 21, 1938, Serial No. 241,534 2. Claims. (01. 206-60) This invention relates to bundling devices for building boards and has reference more particularly to bundles of plaster boards of the per-.- forated type.

In the manufacture and sale of gypsum plaster boards, it has been customary to arrange the boards in bundles with edge strips of paper holding the boards together in bundle form. Such a bundle is described in patent to Birdsey No. 1,696,877. There has also come into use plaster boards with spaced perforations which register in a bundle, these perforations being for the purpose of forming a flrm key with a layer of plaster applied to plaster boards forming a partition. I have found that the perforated plaster boards may be firmly bundled at less expense by attaching means extending through the register and bundling devices in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawing forming a part of this specification, in which Fig. 1 is a perspective view of my improved bundle,

Fig. 3 is a sectional elevation through the bundling device,

In the manufacture of plaster boards, such as those having a gypsum core and paper cover sheets, it is desirable to ship out the boards in viewthrough the bundle form. Such a bundle is illustrated in Fig. 1, in which six boards III are arranged in face to face relation with the edges of the boards in alignment. It is quite common to provide said boards ID with spaced holes or perforations It so that plaster applied to the face of the boards in a wall will more perfectly bond with the boards and improve the fire resistance of the wall. These holes ll may be formed by drilling after the bundle is formed or they may be formed by' punching the boards, either in the damp or dry states. The holes III in the bundle of boards are usually in approximate registry one with the other, The salient feature of my invention constitutes binding means passing through a plurality of holes in the boards of a bundle, in order to bind the bundle of boards together for shipment.

In the form of the invention shown in Figs.

-1, 2. and 3, I provide a large diameter tube l2 which has an outside diameter somewhat less than that of the holes II. An outstanding annular flange I3 is formed at one end of tube I2 and an inwardly extending annular flange I4 is 7 formed at the other end of said tube l2. A tube l5 has an outside diameter somewhat less than the inside diameter of flange [4 into which it telescopes. An outstanding annular flange I6 is formed around one end of the tube 15 so that when the tubes l2 and I5 are in telescoped arrangement in one of the holes II, the bundle of boards will be confined between tube flanges I3 and Hi. In order to lock the tubes l2 and [5- in telescoped relation, I provide a series of struck on the edge of disc 2|.

M, the particular lug in engagement depending on how far the bundle permits the tubes l2 and ii to telescope. The lugs 48 have a certain amount of springiness so that when a lug is depressed to pass the flange i4, it again springs outwardly to look behind the flange M. One of these bundle binding devices may be used adjacent each end of the bundle, as shown in Fig. 1, so as to firmly unite the boards Hi in bundle form. In order to separate the boards after delivery, I provide the workman with a cutting tool comprising a'handle la, a stem 20 and a disc 2! on the end of the stem 20, said disc having an outside diameter somewhat less than the inside diameter of tube [5. 'A cutting point 22 is formed To disengage the bundle, the disc 2| is thrust into the tube t5, the cutting point 22 forming a longitudinal cut 23 in the wall of the tube. The handle !9 is then manually rotated and the cutting point 22 cuts of! the tube l5 and the bundle of boards can then be separated and formed into a wall or partition. A washer 24 secured to stem 20 limits the inward movement of disc 2|.

In the form of the device shown in Figs. 4 and 5, I provide a tube 26 which has a preformed annular flange 21 formed around one end. After a pair of tubes 23 are inserted through bundle holes H, a riveting head 28 forms flanges 29 around the top end of the tube 26 to lock the boards III in bundle form. A cutting tool as previously described may be used to separate the bundle at the job. If desired, both flanges 21 and 28 may be formed simultaneously by opposed riveting heads 28. The tubes l2, l5 and 26 may be made of thin metal, but any other suitable material may be used.

The form of bundling device shown in Figs. 6 and 7 is especially useful where the holes II in the bundle of boards are not in exact alignment, as when the holes are punched prior to bundling before the boards have been dried. In this form of bundling device, I force a strip of metal 3| through holes H of a bundle, said strip 3| being somewhat wider than the diameter of holes so that the strip 3| will force itself through the holes in a bundle whether or not said holes are in exact'registry. A transversely extending preformed flange 32 is formed at one end of the strip 3| and after assembly of the bundling device, the end of the strip 3| is bent transversely to form flange 33, so that the bundle of boards is confined between flanges 32 and 33. One of the flanges 32 or 33 is bent outwardly with a fiat tool at the job to release the bundle of boards l0.

In all forms of the bundling devices, considerable pressure is applied to the bundle at the time of assembly, so that retaining flanges I3, I3, 21, 29, 32 and 33 bite into the exposed surfaces of the boards so as to lie generally below said surface. This is an advantage in that when the bundles are stacked in a pile, the flanges of the bundling devices will not scratch or mar the cover sheets of adjoining bundles.

I would state in conclusion that, while the illustrated examples constitute practical embodiments of my invention, I do not wish to limit myself precisely to these details, since manifestly the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim as new' and desire to secure by Letters Patent:

1. In a bundling device, the combination with a plurality of gypsum composition building boards in face to face abutting relation, said boards having a series of substantially registering holes, of a pair of telescoping tubular members having outstanding flanges at the ends thereof for confining said boards in bundle form, and interlocking means between said tubular members for adjustably connecting said tubular members.

2. In a bundling device, the combination with a plurality of building boards in face to face abutting relation, said boards having a series of substantially registering holes, of a pair of telescop ing tubular members having outstanding flanges at the ends thereof for confining said boards in bundle form, outstanding spring lugs struck from one of said tubular members for adjustably engaging with the other of said tubular members so as to connect said members together in bundle confining relation.
